Emergency Power and Method of Operation
The emergency luminaire power is derived from a 24 hour central emergency
power source. The local utility power company normally supplies the power
through a UL1008 Transfer Switch or equal, but during a utility power failure,
the transfer switch automatically switches to the emergency power source.
The room switch turns on and off both regular and emergency luminaires
simultaneously. This is accomplished by having the room switch leg power
activate the Emergency Power Control, ECS00-110.
Wire input #1 or #2 and neutral are connected internally to a sensing circuit.
During a power interruption on the sensing input, this circuit causes contact X
to drop into a N.C. position and turns on the emergency load(s). Review wiring
diagram for details.
The unit is equipped with a green LED, which indicates if regular utility power is
available and eld sensing wiring is connected correctly.

Automatic Diagnostic Feature
The unique feature of the ECS00-110 is the ability to place the unit above the
accessible ceiling tile because the unit does not require an accessible test
switch. Instead, when the room switch is turned off, the emergency luminaires
stay on for 2.5 seconds and indicate that an emergency power source was
available and that the ECS00-110, ballast, and lamp(s) are all functioning
correctly. This feature replaces a test switch and is approved for this purpose.
Wiring Installation
WARNING: TO AVOID FIRE, SHOCK OR DEATH, turn off power at circuit
breaker on both normal power circuit, 24 hour night light/emergency generator
circuit and test that power is off before wiring.
NOTES:
• It is recommended to number eld wiring.
• Regular room lighting load does not effect ECS00-110 current rating. Room
switch is only used to control ECS00-110 10 mA relay current coil, and regular
lighting load. Regular line HOT connected to breaker and ECS-110 is only
drawing milli-amps to sense if normal power is available.
• In order to provide a safe light level, when regular power is interrupted, it
is recommended that a minimum of two 4 ft uorescent tubes providing
appproximately 5000 lumen are controlled by a 24 hour emergency circuit
and are spaced no farther than 24 ft in any direction from each other in a
normal 9 ft white ceiling environment. The ECS00-110 is a universal type unit,
convenient and fast to install virtually anywhere.

1. Install a self-adhesive 2 in. x 3 in. caution label in each xture or load
controlled by an ECS00-110 unit, cautioning that this load is supplied from
two different power sources, regular and emergency.
2. Review wiring diagram and connect wires, one group at a time, in
accordance with the numeric identication.

Common Wiring Scenarios
One Light Fixture in a room
For some installations which require only a single emergency light in an area
with no regular lighting.
Two 3-Way Switches
When using two 3-way switches in a room to control the lighting from
two locations.
Dual Light Level Switching
For installations with dual light level controls. Can only be used when separate
ballasts are used for A leg and B leg. If using modern bi-level ballasts, contact
manufacturer for appropriate part number.
Wiring as shown will cause only “A” ballasts to operate as emergency xtures. If
all tubes are desired for emergency: use two ECS00-110’s or contact
the manufacturer.

What to do if...
ECS00-110 does not function properly on startup perform the following tests:
• Test Normal Operation: Ensure branch circuit breaker is connected and utility power is available. If GREEN LED is not illuminated, conrm wiring connections and
continuity to branch panels.
• Test Emergency Operation: Ensure emergency source is connected and RED LED is illuminated. Turn room switch to “OFF” position, and ensure that emergency
lights stay illuminated for at least 2.5 seconds. If emergency lights do not stay on for at least 2.5 seconds, conrm wiring connections and perform testing on
emergency panel and emergency power source.
No maintenance is required to keep the ECS00-110 functional. However, regular testing should be performed when the lamps or ballasts have been replaced or
when facility remodeling has taken place.
